The sand crab does not recognize its owner. Sand crabs have low IQs and only know food and will not know their owners. However, feeding them regularly every day can help them form a conditioned reflex and allow them to crawl out to wait for food and no longer be afraid of their owners. You should also be careful when raising them to be careful not to be pinched by them.
Precautions for raising sand crabs:
1. Do not expose sand crabs to the sun for a long time to prevent them from being killed by high temperatures.
2. You can feed sand crabs small fish, shrimps, aquatic plants and other foods, but avoid feeding meat with thick oil.
3. The fish tank needs to be cleaned in time to prevent food residues from contaminating the water quality and affecting the health of the sand crabs.
